SWINGING GATE.

SPECIFICATION forming part of Letters Patent No. 330,937, dated November 24, 1885.

Application filed February 5, 1885. Serial No. 154,997. (No model.)

To all whom, it may concern: l

Be it known that I, WILLIAM H. STARRY, a citizen of the United States, residing at Trenton, in the county of Butler and State of Ohio, `haveinvented certain new and useful Improvements in Swinging Gates; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specilication, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a front elevation of a swinging gate embodying` my invention; Fig. 2, a top plan view of the bracket and itsconnections for supporting and operating the rear end of the gate; Fig. 3, an under plan view thereof; Fig. et, a longitudinal central section taken on line xmof Fig. 2; Fig. 5, a perspective View of the tripping device over which the rim of the vehicle-wheel passes to operate the gate; and Fig. 6, a detail view of the take-up for shortening or lengthening the connecting-rod. A

The present invention has relation to that class of swinging gates operated by the contact ofthe rim of the vehiclewheel with a tripping device connecting the gate with aleverrod.

The object of the present invention is to improve the construction of the mechanism heretofore employed for operating the gate, whereby the usual counterbalance and doublecrank rods are dispensed with and a more perfect action of the operating mechanism obtained. These objects I attain by the construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents the gate, provided with brace-rods c, said gate being hinged to the post B, and retained closed by a latch, b, engaging with a keeper, c, on post C. The rear batten, cl, of the gate, at the upper end thereof, is connected to the post B by the usual hinge, as shown at e, and to the lower end of the hatten is bolted the pivot-armf. The lower end of the arm f is formed cylindrical, and extends down through an elongated opening, g, in the horizontal portion of a bracket, D, secured to the post B. The pivot-arm f is provided with a collar, h, and between this collar and the bracket are placed levers E, the inner ends tting loosely over the pivot-arm and bearing against fulcruni-blocksi on the bracket, while the outer ends of the levers are supported by flanges k. The lower end of the bolt]c passes through an elongated opening, Z, in a plate, F, pivoted at its outer end to the underside of the bracket D. A curved spring, G, bears against the under side of the plate F, its free end working in a groove or mortise, m, in the plate, to return the plate to its normal position when closing the gate. The plate F, which I term 4 a locking-plata7 is disengaged from pivoted dogs n by being depressed, as shown in dotted lines, Fig. 4, thus allowing the plate to be carried along with the pivotarmf when moving in the slot y in opening the gate. This depression of the plate F is caused by the action of the beveled end of a tongue, o, projecting from the pivot-armf, acting on the correspondingly-beveled face of a lug, p, upon the locking-plate when the pivot-arm moves forward in the slot To the ends of the levers E are connected one end of rods H, which are screw-threaded to engage with screw-threaded holesin blocks I, thus providing a take-up for the rods to adjust them to cold and heat, or compensate for contraction and eXpansion,by lengthening or shortening the rods from the point of attach ment at their extremities. rlhe blocks I are pivoted to the under side of the levers E,so that the latter will freely operate by means of their swivel-connection with the rods. Theopposite ends of the rods H are connected to triplevers J, one upon each side ofthe gate. The lever J is pivoted to a support, r, which is bolted to a base, K, sunk into the ground, so that its upper edge will be iush therewith. The pivoted triplever J is formed with a curved elbow, s, and terminates in a double incline, t a, at its free end, over which travels a friction-roller, w, upon a crank, L, pivoted to the sidesof the base K. The normal position of theV trip-lever and its connections when the gate is closed is shown in full lines, Fig. 5. Vhen a vehicle passes in the direction of the arrow, the rim of the wheel will depress the pivoted crank L as it passes over it. This action upon the crank lh will cause it and the friction-roller w to pass over the curved shoulder s of the lever J, as shown in dotted lilies, a space, y, being provided at the IOO , Z, which raises the front end of the gate and unlatches it. At the same time that the pivotarmf moves forward in the slotsg` Z the tongue o, acting against the lug p, depresses the looking-plate F, thereby releasingit from the dogs u, which allows the pivot-arm to move trans` versely in the slot g, carrying with it thelocking-plate, and throwing the gate out of balance to open in an opposite direction to the tripping device over which the vehicle-wheel has passed. The trip-lever and its connections at the opposite side of the gate still remain in their normal position until acted upon by the passing vehicle-wheel, when that tri p-lever is in like manner depressed, bringing the pivotarrn f back to position, carrying the plate F with it, so that the plate will be in line with the pivoted dogs n, when the spring G will press the plate upward into engagement therewith to hold it stationary and lock it in position, thus causing the gate to swing to its closed position.

Having now fully described'my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In asw-inging gate, the combination, with atripping device composed of a pivoted lever having a curved elbow and incline, of a hinged connection for the gate, consisting of a bracket, a locking-plate pivoted thereto, a

pivot-arm connected to the gate and supported in the bracket, and levers ior operating said arm and plate, substantially as and for the purpose set forth.

2. In aswinging gate, the combination, with a tripping device, of a hinged connection for the gate, consisting of a bracket provided upon its under side with a locking-plate pivoted thereto, a spring for automatically pressing the plate into engagement with dogs upon the bracket, a pivot-arm secured to the gate and supported in the bracket, levers for operating said arm and locking plate, and i'ulcrumblocks upon the upper side of the bracket for the levers, substantially as and for the purpose speciiied.

3. In a swinginggate, the combinatiomwith a tripping device, of a hinged connection for the gate, consisting ofa bracket provided with a pivoted locking-plate, having a beveled-face lug and a slot, and a pivot-arm operated by levers, and provided with a tongue having a beveled end to act against the face of the lug,

substantially as and for the purpose described. v

4. In aswinging gate, the combination, with a tripping device, of a hinged connection for the gate, consisting of a bracket, a pivoted arm supported thereby, levers for operating the arm, blocks to form fulcrums for the levers,

a pivoted locking-plate, and a spring toact on the plate, substantially as and for the purpose set forth.

A hinged connection for an automat-l ically-operating gate, consisting of a pivotarm connected to the gate, having a beveled tongue, and levers for operating the arm, in combination with a bracket having a slot or opening, fulcrun'l-blocks for the levers, and a pivoted and slotted locking-plate provided with a beveled lug, and a spring for pressing the plate upward in engagement with dogs upon the bracket, substantially as and for the purpose specified.

6. A tripping device for automaticallyswinging gates, consisting of a pivoted triplever having a curved elbow and double ineline, as shown, in combination with a pivoted crank for operating the lever, substantially as and for the purpose described.

7. In a swinging gate, a hinged support for connecting the same to the gate-post. consisting of a bracket, a pivot-arm, and pivoted locking-plate, in combination with levers for operating the pivot-arm, having at their free ends pivoted blocks, and rods connected thereto and to pivoted trip -levers formed with curved elbows and double inclines, and pivoted cranks for operating the same, substantially as and for the purposeset forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
